Although the technical info is beyond me this one really looks interesting: "Human milk may contain components of HIV but it also contains factors such as the glycosminoglycan chondroitin sulfate which inhibits the binding process. It is of interest to note that other body fluids such as saliva also contain HIV nucleic acids but are generally not considered important vehicles of HIV transmission due to the presence of similar inhibatory molecules. The authors suggest several other research focuses and recommend continued careful evaluation of HIV transmission from mother to infant via human milk in light of their results."
